Chronic obstructive pulmonary disease (COPD) is a general term for a group of lung diseases, including emphysema and chronic bronchitis. People with COPD have decreased airflow in and out of the lungs, which makes it hard to breathe. The airways also can get clogged with thick mucus. Cigarette smoking is a major cause of COPD.
Although there is no cure for COPD, you can slow its progress. Stopping smoking, following your treatment plan and taking care of yourself can help you feel better and live longer.
